- There is an even more "amazing" fact, it's proved that there is a "Harmonic model of gas" so its total partition funciton Z is equal to the riemann Zeta function..(If Bosons) and [tex] \zeta(2s) / \zeta(s) [/tex] (If Fermions).. the frecuencies of every particle (infinitely many of them) is [tex] \hbar \omega (k) = log(p_k ) [/tex] k=1,2,3,4,5,... (primes) this is called the "Riemann Gas"...

I can't find much on that but would love to learn more do you have links to some references?

Unfortunately "Playdo" i myself am stuck in this problem.. you could try to learn something about "Statistical Physics" (involving partition function) at Wikipedia

So do you usually make statments of fact about things you cannot completely prove? I mean it is one thing to be armchair and point to someone elses clearly written work, but to simply say I think this is true but can't prove it. At least make an argument showing why you think it might be true or even what you really mean.

Using Solid state (i recommend you "Ashcorft & Mermin : SOlid State Physics) using the definition of Partition function and specific Heat.. i've been able to recover the Integral equation involving [tex] \pi (e^{t}) [/tex] (precisely the inverse of the k-th frequency) [tex] \omega (k) = log(p_k) [/tex] ,unfortunately this does not simplify the problem.. what i have asked is if there would be a method knowing the "Entropy" , "gibbs function" or similar ,which can be calculated knowing the partition function, and from this to get the density of states (in 1-D is just the inverse of the derivative [tex] \frac{d\omega}{dk} [/tex] multiplied by a constant, if we were able to calculate the "speed of sound " for the lattice or density of states we could calculate every prime..at the moment the only chance would be to use X-rays (if we had a portion of the Riemann gas of course) to calculate the frequencies... of course this is impossible since Riemann gas does not exist
